When water is heated under atmospheric pressure, two things occur. One is a change in temperature. The other is a change in phase. These two properties will be studied to determine the heat of fusion and the heat of vaporization of water. The purpose of this experiment is to determine the heat of fusion and the heat of vaporizaton of water.

For the ring stand, use the metal rods in D89 and the tripod bases that are next to the ice machine, if possible. Make sure the rods fit the bases. Clamp on the test tube clamp and slide it down the rod.
Make sure that the room has plenty of paper. Fill the two coolers with ice. Ice must be acquired near classtime from friends in the Biology or Chemistry Departments. If you cannot be present to get ice nor arrange for someone else to, please inform the instructor as soon as possible.
